The invention provides a bogie frame and a suspension type railway vehicle, and relates to the technical field of suspension type railway vehicles, the bogie frame comprises a bogie frame upper beam and two bogie frame lower beams, the bogie frame upper beam is of a T-shaped integrated structure, the lower end of the bogie frame upper beam is suitable for being connected with a suspension beam, the two bogie frame lower beams are arranged on the two side faces of the lower end of the bogie frame upper beam respectively. The bogie frame is arranged to be of the structure, so that the lower end of the upper beam of the bogie frame can be directly connected with a corresponding structure similar to a suspension beam, the weight of the corresponding structure is borne by the upper beam of the bogie frame, and due to the fact that the upper beam of the bogie frame is of the T-shaped integrated structure, the strength of each section of the upper beam of the bogie frame is similar. Therefore, unstable points do not exist, the vertical bearing capacity of the bogie frame is high, and the overall strength of the bogie frame is high.
本发明提供了一种转向架构架及悬挂式轨道车辆,涉及悬挂式轨道车辆技术领域,包括转向架构架上梁和两转向架构架下梁,所述转向架构架上梁为T形的一体结构,所述转向架构架上梁下端适于与悬吊梁连接,两转向架构架下梁分别设于所述转向架构架上梁下端的两侧面。通过将转向架构架设置为上述结构,从而使转向架构架上梁下端可直接与类似悬吊梁的相应结构相连接,进而由转向架构架上梁来承受相应结构的重量,由于转向架构架上梁为T形的一体结构,则转向架构架上梁上各截面的强度是近似的,因此,不存在不稳定点,从而使得转向架构架的垂向承载能力较高,并使得转向架构架的整体强度较高。
